Dryers are a great way to get your clothes dried in a relatively short amount of time. However the costs of running a dryer constantly will definitely result in electricity bills that may give you a heart attack, which is why Miele has unveiled what they're calling the "world's first" dryer to use the heat of the sun to dry your clothes. If that sounded a bit weird, they aren't talking about the heat of the sun in the literal sense where you actually hang your clothes out in the backyard for it to dry, but instead it will utilize the heat gathered by rooftop solar-thermal collectors.
